The MSI B850-P Pro is the board 3mbdeb chose. If you're an enthusiast for this kind of stuff, you can now take openSIL for a spin before it shows up with AMD's next-generation CPUs, though the firm warns that this is a "proof of concept" that is "not intended for production use." Work on getting openSIL plus Coreboot on the MSI board is based on earlier work surrounding the Gigabyte MZ33-AR1, a server board designed to run AMD's EPYC 9005 series CPUs. AMD published its openSIL initialization code for the aforementioned Turin server chips well before AMD published the same code for its desktop Phoenix CPUs. As a result, the B850-P Pro is benefiting from the development work already put into the aforementioned Gigabyte board.

Silicon firmware like openSIL and AGESA are responsible for making sure major components hooked up to the motherboard are operational, and initiate key components such as the CPU, RAM, and chipset. Without these microcode platforms, your computer would not boot at all. They serve as part of the larger firmware stack, connecting the silicon to the host firmware, such as UEFI, or in this case, Coreboot.
